Fishing all night, I used to bring out the Coleman dual fuel lantern. Easily get the whole night on a full tank of kerosene.
I had once also built myself an area light box. Had two flasher 7ah batteries and used automotive fog lights. That didn’t work out and was only good for a few hours at most. Now with so many new led strips 12v application, I could redo my area light box.
However I since I own a few Ryobi tools for home use, I bought into a work light.
18V ONE+™ HYBRID LED PROJECT LIGHT #P790
Three settings of 900 lumens, 600 lumens, and 100 lumens. Low power suppose to give 35 hours of light on a high capacity battery that’s the P105 battery, maybe equals a typical 3ah. I left the light on low mode with my 3ah battery, still shining bright when I woke up 8 hrs later.
I also have several pocket work lights. The cheap kind made with led lights and you find in the gift light section. I bought them for $1.50 on clearance at one time for the cost of less than batteries. I got mine at Menards by the brand Smart Electrician. I’ve used these overnight a few times while catfishing summertime, on the lowest spot led mode instead of using chemical light sticks or those little led sticks for rod watching in the dark. Still haven’t replace batteries in them yet. They have hooks and magnets, so they are great light source in the corners of the hub shack as well.
